FAIRHAVEN — Authorities are searching tonight for a missing, 21-year-old Marion man, last seen when he left his home with a kayak to go duck hunting, police said.

The Coast Guard identified the man as Dana Dourdeville. A Coast Guard spokeswoman said Dourdeville was scheduled to return at sunset and his mother reported him missing at 7:42 p.m.

The Fairhaven Police and Fire departments, the harbormaster, a state police helicopter, New Bedford police marine unit and the Coast Guard have all been involved in tonight's search, according to Sgt. Kevin Kobza, public information officer of the Fairhaven Police Department.

At 10 p.m., the Coast Guard spokeswoman said a 45-foot response boat from Woods Hole and a helicopter from Air Station Cape Cod are taking part in the search.

In temperatures hovering around 20 degrees, authorities are searching the entire Little Bay area, starting from the east side of West Island and including all the conservation lands, according to Kobza. The search also extends to the Brandt Island Cove area in Mattapoisett.

The hunter was last seen about 2 p.m. today when he left his Marion home, Kobza said. The man is believed to have gone duck hunting alone.

After he failed to return home, his mother went looking for him, according to police. His vehicle was found in the town beach parking lot of West Island about 7 p.m., but as of 9:45 p.m., police had not located his red, 9-foot kayak.

The missing hunter is described as about 5'10” tall, thin build with brown hair, Kobza said. He was wearing brown sweatpants and a red life jacket.
